Where Qwen3.8 Flash sits on price
At $0.47 per million output tokens, Qwen3.8 Flash is a budget tier model — 4.7× cheaper than the median output price of $2.20, which puts it cheaper than 80% and pricier than 20% of the models we track. It sits 15th cheapest of the 53 Alibaba (Qwen) models we track. Output costs 3.1× input, the usual spread — trim both, starting with the answer length.
Cached input is 89% cheaper. On an input-heavy workload you need roughly a 28% cache-hit rate to take 25% off the input line — reachable for chatbots and agents that resend the same system prompt and history.
What real workloads cost on Qwen3.8 Flash
These three workloads are the ones teams actually run on a budget-priced model — a $0.47/1M model is not bought for the same job as one ten times the price.

| Small app — 1K requests/day (500 in / 150 out) The baseline most side projects actually run at. | $0.0001 | $4.36 |
| Long-context analysis — 200 runs/day (250K in / 4K out) Only possible on large-context models; input cost is nearly the whole bill. | $0.0394 | $236 |

› Is Qwen3.8 Flash worth the price?
Qwen3.8 Flash is in the cheapest end of the market — cheaper than 80% of the models we track.
